LIMB MEASUREMENTS. 109 



included between 32 and 34. Since the averaoe of the numbers, which ia 

 33 -3, nearly corresponds with the value of the median, we may take it as 

 representinc; the proportion which the length of the upper limb bears to the 

 height of the body amongst these natives. 



(6) The proportion of the length of the lower limb to the height of the body, 

 taking the latter as 100. The range of these 27 indices is 46"9 to 51'6. 

 Two-thirds of the total number are included between 48 and 50 ; and since 

 the average of the numbers, which i? 49*1, corresponds nearly with tlie value 

 of the*middle index of the scries, we may take it as representing the propor- 

 tion that the lower limb usually bears to the height of the body amongst 

 these natives.

(7) The span of the outstretcheJ arms. — The following indices— 69 in 

 all— show the ratio of the span of the arms to the height of the body, 

 taking the latter as 100 : —

The range of theso indices is 100 to 112-6; and the indices of greatest 

 frequency are those included between 106 and 107. Placing all the indices 

 in their order, T find that the value of the central of the series is 106-7, and 

 of the quarter-points 105-2 and 108-6 respectively. Taking 106-7 as repre- 

 senting the average proportion which the span of the arms bears to the 

 stature amongst these natives, I may compare it with similar results given 

 for other races in Topinard's Anthi-opology : — 



American soldiers (10,876), ... ... ... 104-3 



Solomon Islanders (69), ... ... ... 106-7 



Negroes (2020), ... ... ... -.- 108-1
